Thread-topic:	[Xen-users] 16GB limit for PAE?

Its not that, its time constraints.  We have a automated system of building, 
deploying, creating, snapshoting, and destroying VM's.  The servers, dom0 and 
domU are built on Centos 4.4 i386 release.  I don't have the time to rebuild 
the environment using x86_64.  The system started on small 32bit machines and 
has now moved to large 64bit machines.  When I have time I will rebuild the 
environment using 64bit.  The question is now that I'm getting a 32GB machine, 
am I forced to go through the effort of rebuilding to x86_64?

You really want to pay the speed penalty for using a 32bit kernel?
